This list comes from community-sourced LeetCode company lists. It covers coding questions only. It does not tell us how many rounds Reddit runs, what each round covers, or what it pays, and those change by role, level and team, so we do not list them. Ask your recruiter what each round covers, and check the company's careers page.

Prepare for the rest of the loop with the coding interview patterns guide, the system design framework, and the STAR method guide. Written by Kieron.

Tips for Success at Reddit

Start with the 5 most reported Reddit questions, then work down the list.
Mediums are the bulk of the list (60%), so spend most of your time there.
Time yourself: 20 to 30 minutes per medium, then explain your solution out loud as if to an interviewer.
After each problem write down the pattern and the signal that revealed it. Patterns transfer to problems you have not seen.
Pair coding practice with a system design framework and prepared behavioral stories; most loops include more than coding.

Frequently Asked Questions

How many LeetCode questions should I practice for Reddit?

There is no fixed number. Start with the 5 most reported questions in this list, learn the patterns behind them, and then sample from the rest. The list has 5 reported questions, which is more than anyone needs to solve; patterns matter more than volume.

Are these the actual Reddit interview questions?

No. They are questions that candidates reported seeing, collected in community LeetCode lists, and they may be out of date. Interviewers change problems, so use the list to practice patterns, not to predict your interview.

What is the difficulty mix for Reddit?

Of the 5 reported questions, 1 are easy, 3 medium and 1 hard (20%, 60% and 20%). This reflects what candidates reported, not what you will necessarily be asked.

What is the Reddit interview process?

It varies by role, level and team and it changes, so this page does not list rounds or pay. Ask your recruiter what each round covers, and check the company's careers page for current information.

How do I prepare beyond coding questions?

Practice a system design framework for design rounds, prepare five or six behavioral stories with the STAR method, and run mock interviews out loud. See the linked guides on this page.
